How much salt is in seawater? How much blue dye is in that fruit drink? Or how much sugar is in your can of soda? Chemists have many ways to measure the concentration of various substances in solutions. To measure the amount of salt in seawater, for instance, they might measure how well the solution conducts electricity, since the higher the level of dissolved salt, the higher the electrical.

The Roman Catholic Church later changed the day of celebration to December 25, calling it Christmas. Consider the pagan roots of our popular symbols of Christmas: (1) Christmas Tree – The sacred tree of the winter-god; Druids believed the spirit of their gods resided in the tree.Most ancient pagans knew the tree represented Nimrod reincarnated into Tammuz!

When dissolved in water, formaldehyde also forms a hydrate, methanediol, with the formula H 2 C(OH) 2.This compound also exists in equilibrium with various oligomers (short polymers), depending on the concentration and temperature. A saturated water solution, of about 40% formaldehyde by volume or 37% by mass, is called "100% formalin".A small amount of stabilizer, such as methanol, is usually.
